Data Loss due to power down (CR1000X)

firminf Oct 6, 2022 04:17 PM


I loss power on a CR1000X datalogger on the field due to cable disconnection.

I tried to collect data with USB connection without compiling any program or modifying USR memory.

I can't have acces to the older records when I try to collect trhough LoggerNet or PC200W.

Is there any way to retrieve this data?

Best regards

You can try the data recover utility in Device Configuration Utility. If something can be retrieved, it can find it.

There are two types of data storage in the CR1000X; battery back RAM and flash memory. If the lithium battery was run down, you would lose all data in RAM when main power was lost.

Data is only duplicated onto the flash memory if the size of the data table is set to autoallocate(-1).

Thanks for your reply.

There is no data in the Device configuration Data Collection section.

The lithium battery seems to be right (3.66V).

The parameter of autoallocation "-1" is well defined for both data tables.

On the other hand there is a time shift of 8h...

I read a topic on the forum that commands can be send trough the terminal to refill some datatable. It was for a similar issue with a CR1000.

Is there an equivalent for CR1000X ?

Best regards,

Use the Data Recovery option found in the Backup menu of Device Configuration Utility.
